主　　题：Jincheng orange volatile compounds fatty acids growth stages 

摘      要：Jincheng orange(Citrus sinensis Osbeck)is widely grown in Chongqing,China,and is commonly consumed because of its characteristic aroma contributed by the presence of diverse volatile *** changes in aroma during the development and maturation of fruit are indicators for ripening and harvest ***,the influence of growth stages on the volatile compounds in Jincheng orange remains *** addition,volatiles originate from fatty acids,most of which are the precursors of volatile *** this basis,gas chromatography-mass spectrometry(GC-MS)was performed to elaborate the changes in volatile constituents and fatty acids as *** study tested proximately 60 volatiles and 8 fatty acids at 9 growth and development stages(AF1-AF9).Of those compounds,more than 92.00%of total volatiles and 87.50%of fatty acids were terpenoid and saturated fatty acids,*** shown in the PCA plot,the AF5,AF6,and AF9 stages were confirmed as completely segregated and appeared *** addition,most of the volatiles and fatty acids first increased at the beginning of the development stage,then decreased from the AF6 development stage,and finally increased at the AF9 maturity ***,the highest contents of terpenoid,alcohols,aldehydes,ketones,and saturated fatty acids in Jincheng orange peel oil were d-limonene,linalool,octanal,cyclohexanone,and stearic acid during development stages,*** results found that the growth stages significantly affected the volatile constituents and precursors in Jincheng orange peel oil.
